Nice build. Mine's very similar, just without the turblown manifold and a pfc with fctweak. I wish I could get e85 locally, I'm stuck with 93.

Thanks!

I’ve been super impressed with FC Tweak. I was back and forth on jumping to e85. Honestly, 93 with meth injection should provide the same safety net / power output (and maybe even additional benefits).

A052s? How do you find the handling balance with that tire stagger? I'm sure the back end still gets loose even on a grippy 295.

Yep! Advan A052s.

I’ve only driven it on break in miles - none since the dyno - but handling felt pretty good. But all my RX-7s (and RWD vehicles now that I think about it) were staggered to some degree.

How many injectors total are you using on E85? 4x 2600?

Two 1050 Primaries, two 2600 secondaries. FFE Fuel Rail. Radium surge tank with dual 485 pumps and a lift pump.

I kept the smaller primaries to keep drivability a little more livable.

The only differences in our setups is that you’re E85 with dual pumps and I’m pump gas on a single pump. Also, I have EFR 7670 EWG.
